Ventilatory threshold is one of the ways to measure cardiovasculatory fitness of the body. Therefore, in the present study it was decided to demonstrate which physiological parameters most accurately express the second ventilatory threshold (VAT2) depending on the cardiovasculatory fitness of different groups of athletes and untrained men. The study involved the following athletes: race walkers (n=14), weightlifters (n=16), powerlifters (n=16), runners (n=14), professional soccer players (n=13), amateur soccer players (n=16), martial arts (n=12), and untrained men (n=15). Subjects’ VAT2 and maximal load (ML) were recorded and at these levels were determined the value of achievable maximal power (P), oxygen uptake (VO2), heart rate (HR), the ratio for oxygen uptake and heart rate (VO2/HR) and the rate-pressure produkt (RPP). It was shown that subjects were of similar age but different body mass (BM) and BMI. There were also differences between athlete groups at VAT2 and ML in relation to: P, VO2, VO2/HR (p

Obesity is an unfavorable state of health as a result of which come in the initial adaptation, that couldgradually transform into specific disease condition. The aim of the study was to assess the degree ofmiddle-aged men adaptation to obesity in terms of somatic changes, exercise capacity andcardiopulmonary fitness. The study involved 12 obese middle-aged men (OG) - BMI = 34.32 ± 4.11kg/m2. The control group (CG) consisted of 12 non-obese middle-aged men- BMI = 23.72 ± 1.83 kg/m2,with similar body height (BH) to OG. After recording somatic and physiological data at rest,participants were subjected to the bicycle ergometer test (BT) gradually increasing intensity. Duringthe BT aerobic power (AP) was recorded and analyzed along with parameters characterizing theefficiency of the circulatory and respiratory systems at anaerobic threshold (AT) and the maximum load(ML). This study has shown that obese men have a higher body mass (BM), a higher content of fat (BF),an increased lean body mass (FFM) and a higher content of water (TBW) than CG (p
